    3. SFP ports support hot-swappable functionality, allowing modules to be inserted or removed without powering down the switch.
  2. Flexibility:
    1. SFP ports offer flexibility in network connectivity by supporting a wide range of SFP modules or transceivers.
    2. They can accommodate various types of optical or copper cables, including multi-mode or single-mode fiber optics, and different Ethernet standards (e.g., 1Gbps, 10Gbps, etc.).
    3. SFP ports can be used for different networking technologies, such as Ethernet, Fibre Channel, or SONET/SDH.
  3. Module Compatibility:
    1. SFP ports are compatible with SFP modules or transceivers that match the desired network requirements (e.g., speed, distance, media type).
    2. Cisco offers a variety of SFP modules tailored to specific networking needs, including Gigabit Ethernet, 10 Gigabit Ethernet, and Fibre Channel.
  4. Configuration and Management:
    1. SFP ports are configured and managed through the Cisco switch's command-line interface (CLI) or graphical user interface (GUI).
    2. Administrators can configure port settings such as speed, duplex mode, VLAN membership, and other parameters to optimize network performance and reliability.
  5. Monitoring and Diagnostics:
    1. SFP ports provide monitoring and diagnostics capabilities to track port status, link status, and performance metrics.
    2. Administrators can use tools like Cisco's Embedded Event Manager (EEM) or Simple Network Management Protocol (SNMP) to monitor SFP port activity and detect any issues or abnormalities.
  6. High Availability and Redundancy:
    1. SFP ports support features like link aggregation (EtherChannel) and redundancy protocols (such as Spanning Tree Protocol) to enhance network reliability and availability.
    2. Multiple SFP ports can be aggregated together to increase bandwidth and provide failover capabilities in case of link failures.

Benefits of SFP & SFP+

SFP (Small Form-factor Pluggable) ports offer several benefits for network connectivity in various environments.

  1. Flexibility: SFP ports provide flexibility in network connectivity by supporting a wide range of SFP modules or transceivers. This allows for the use of different types of optical or copper cables, including multi-mode or single-mode fiber optics, and various Ethernet standards (e.g., 1Gbps, 10Gbps, etc.).

2. Modularity: SFP ports are modular interfaces that can accommodate hot-swappable SFP modules or transceivers. This modular design allows for easy replacement or upgrade of networking components without disrupting network operations or requiring downtime.

3. Scalability: SFP ports enable scalability in network design by allowing administrators to add or remove ports as needed to accommodate changing network requirements. This scalability makes SFP ports suitable for both small-scale and large-scale networking deployments.

4. Cost-Effectiveness: SFP ports offer cost-effective solutions for network connectivity by allowing administrators to choose the appropriate SFP modules or transceivers based on their specific networking needs. This flexibility helps optimize costs by avoiding the need for unnecessary hardware investments.

5. Interoperability: SFP ports facilitate interoperability between different networking devices and technologies by supporting industry standard SFP modules or transceivers. This interoperability allows for seamless integration of networking components from different vendors, enhancing flexibility and compatibility in network design.

6. High Performance: SFP ports support high-performance networking capabilities, including high-speed data transmission rates and low-latency communication. This makes them suitable for demanding applications and environments that require high bandwidth and reliable connectivity.

7. Space Savings: SFP ports have a small form-factor design that helps conserve space on networking devices, such as switches and routers. This space-saving design is particularly beneficial in environments with limited rack space or where compact networking equipment is preferred.

8. Future-Proofing: SFP ports provide a future-proofing mechanism for network infrastructure by supporting the latest advancements in networking technology. Administrators can easily upgrade SFP modules or transceivers to take advantage of new features or higher performance standards as they become available.

  1. Identify the SFP Port:
    1. Locate the SFP port on the Cisco switch. The SFP ports are typically located on the front panel of the switch and are often labeled with a port number and/or description.
  2. Prepare the Cable:
    1. Cable which is already plugged in ESX host (Validate on one ESX host(ESX01))
    2. Unplug the cable from the SAN Switch (One connectivity from ESX host)
    3. Ensure that the cable you intend to plug into the SFP port is compatible with the SFP module installed in the port. Verify that the cable connector matches the port type
  3. Remove the SFP Module Cover (if applicable):
    1. If there is a cover or dust cap protecting the SFP port, carefully remove it to expose the port(On Cisco Switch)
  4. Insert the Cable Connector:
    1. Align the cable connector with the SFP port and gently insert it into the port until it clicks into place. Ensure that the connector is inserted straight and evenly to avoid damaging the port or connector.
  5. Secure the Cable:
    1. Once the cable connector is fully inserted into the SFP port, secure it in place by tightening any locking mechanisms or screws on the connector, if applicable

vTPM Windows 11 installation in VMware step by step


What is a vTPM? A virtual Trusted Platform Module (vTPM) as implemented in VMware vSphere is a virtual version of a physical TPM 2.0 chip, implemented using VM Encryption. It offers the same functionality as a physical TPM but is used within virtual machines (VMs).

Deployment of vTPM modules, require a Key Provider on the vCenter Server.
For more information on vTPM modules.

In order to deploy vTPM modules (and VM encryption, vSAN Encryption) on VMware vSphere ESXi, you need to configure a Key Provider on your vCenter Server.

Traditionally, this would be accomplished with a Standard Key Provider utilizing a Key Management Server (KMS), however this required a 3rd party KMS server and is what I would consider a complex deployment.

VMware has made this easy as of vSphere 7 Update 2 (7U2), with the Native Key Provider (NKP) on the vCenter Server.

The Native Key Provider, allows you to easily deploy technologies such as vTPM modules, VM encryption, vSAN encryption, and the best part is, it’s all built in to vCenter Server.

Enabling VMware Native Key Provider (NKP)

To enable NKP across your vSphere infrastructure:

->Log on to your vCenter Server
->Select your vCenter Server from the Inventory List
->Select “Key Providers”
->Click on “Add”, and select “Add Native Key Provider”
->Give the new NKP a friendly name
->De-select “Use key provider only with TPM protected ESXi hosts” to allow your ESXi hosts       without a TPM to be able to use the native key provider.

In order to activate your new native key provider, you need to click on “Backup” to make sure you have it backed up. Keep this backup in a safe place. After the backup is complete, you NKP will be active and usable by your ESXi hosts.

Steps to Upgrade VxRail vCenter.

Before starting VxRail infra upgrade you need to go with pre-validation test using vCenter and command line using VxRail Manager.


Please take some time to review the Customer Preparation Guide KB: 


VxRail Engineering performed a data analysis, which has shown that 92% of upgrades complete with no issue when the ESXi nodes are proactively rebooted. This will identify VM's with potential vMotion issues, ESXi maintenance mode issues, reboot issues and refreshes all ESXi services.  

Therefore, RPS are recommending customers to perform a rolling reboot on the ESXi nodes, several days before the VxRail Upgrade (Customer Task).

If a customer has any issues during the reboots, they can open an SR with the VxRail Support team to address an issue.
Additionally, your Upgrade Engineer will also reboot all Service VM's (VxRail Manager, vCenter** & PSC**) and reset iDRAC on all nodes prior to starting the upgrade.
**Only if VxRail Managed. 


 1.      Run Skyline Health

Login to Vxrail vCenter -> Cluster -> Monitor

Under the vSAN Run Skyline



2. Check Resyncing Objects

Login to VxRail vCenter -> Cluster -> Monitor

Under the vSAN -> Resyncing Objects

If all object has already resync then it’s fine if not, then run the Resync from Configuration.



3.      Change VxRail cluster heartbeat duration to repair Object, default it is set to 60 Minutes.

Change it to 300Minutes or more to avoid object sync during node isolation.


Login to VxRail vCenter -> Cluster -> Configuration

Under the vSAN -> Service -> Advanced Option

Click Edit and set Object repair timer.




4.      Enable VxRail health Monitoring.



Login to VxRail vCenter using root credentials and below command to check health status.

Command -> vsan.whatif_host_failures 0



Download vxverify_XXX_XX_XXX.phy file



Open vxverify_XXX_XXX_XX file using phython


Once you will run this command, VxRail manager will start collecting health report like below.



 In preparation for your upcoming upgrade event, note the below known items:

Schedule the upgrade for a time outside of your peak I/O load, as performance degradation may occur during the migration of VMs while individual nodes or hosts are being upgraded.

Since VMs are vMotioned as part of the upgrade, ensure that VMs are available to be vMotioned in advance. Examples of issues which may prevent vMotion:

VM with an ISO mounted.

VM with external storage locally mounted

VM pinned to a host (Affinity rules)


Download the latest ISO from dell portal for VxRail upgrade.

Mount the ISO in VxRail cluster

Login to vCenter -> Select Cluster -> Configuration

Under VxRail -> Updates -> Local Updates 

Select Update Bundle and Upload

Once ISO Image upload complete click start.

Once you click start it will go with Precheck -> Scan and then Update.

Now all the tasks will complete auto. first will upgrade vCenter -> ESXI host.

It will prompt to enter Temp IP that will be assign temporarily to vCenter during upgrade.
